Question

Solve the system by substitution.
-4.5x - 2y = -12.5
3.25x - y = -0.75

Answer 1

oi wrong forum

(1)
-4.5x - 2y = -12.5
isolate
y= (12.5 -4.5x)/2

substitute into (2)
3.25x - y = -0.75

3.25x-((12.5-4.5x)/2) = -0.75

6.5x-12.5+4.5x=-1.5

11x=11

x=1

substitute into (1) y= (12.5 -4.5x)/2

y=(12.5-4.5(1))/2

y=4
