How to solve 3 step linear equations

WebTo solve a system of equations using substitution: Isolate one of the two variables in one of the equations. Substitute the expression that is equal to the isolated variable from Step 1 into the other equation. This should result in a linear equation with only one variable. Solve the linear equation for the remaining variable. WebOct 6, 2024 · To make the calculations simpler, we can multiply the third equation by 100. Thus, x + y + z = 12, 000 ( 1) − y + z = 4, 000 ( 2) 3 x + 4 y + 7 z = 67, 000 ( 3) Step 1. Interchange equation (2) and equation (3) so that the two equations with three variables will line up. x + y + z = 12, 000 3 x + 4 y + 7 z = 67, 000 − y + z = 4, 000 Step 2.
