array must be inside a math environment; this could be fixed by enclosing it in \[ \] the alignment within the array must be specified; for this, \begin{array}{l} would work the primes (input as apostrophes) are defined to be superscripts, so the explicit ^ is unwanted
- 5. 3: Solve Systems of Equations by Elimination
Solve the system by elimination \(\left\{\begin{array}{l}{4 x-3 y=9} \\ {7 x+2 y=-6}\end{array}\right \) Solution In this example, we cannot multiply just one equation by any constant to get opposite coefficients So we will strategically multiply both equations by a constant to get the opposites
- Solve system equation $\\left\\{ \\begin{array}{l} xy - x - y = 1\\\\ 4 . . .
Solve system equation : $$\left\ { \begin {array} {l} xy - x - y = 1\\ 4 {x^3} - 12 {x^2} + 9x = - {y^3} + 6y + 7 \end {array} \right ,\quad (x,y\in\mathbb {R}) $$ My solution begin with : Set $z=x-1
- Matrices and other arrays in LaTeX - Trinity College Dublin
Matrices and other arrays are produced in LaTeX using the \textbf {array} environment For example, suppose that we wish to typeset the following passage: -g -h \lambda - i \end{array} \right| \] First of all, note the use of \left and \right to produce the large delimiters around the arrays As we have already seen, if we use
