Question

can someone just explain how solve a system of linear equation by substitution pleaseee in need of helpp​

Answer 1

Step 1 : First, solve one linear equation for y in terms of x

Step 2: Then substitute that expression for y in the other linear equation. You'll get an equation in x

Step 3: Solve this, and you have the x-coordinate of the intersection.

Step 4: Then plug in x to either equation to find the corresponding y -coordinate.
