Answer:
x = 4.5
y = -5
Step-by-step explanation:
2x - 3y = 24 2x + y = 4
y = -2x + 4
2x - 3(-2x + 4) = 24 y = -2(4.5) + 4
2x - (-6x + 12) = 24 y = -9 + 4
2x + 6x - 12 = 24 y = -5
8x - 12 = 24
8x = 36
x = 4.5
Answer:
x= 3, y= 4
Step-by-step explanation:
y= 3x -5 -----(i)
y= -x +7 -----(ii)
Substitute (i) into (ii):
3x -5= -x +7
3x +x= 7 +5
4x= 12
x= 12 ÷4 <em>(</em><em>÷</em><em>4</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
x= 3
Substitute x= 3 into (ii):
y= -3 +7
y= 4
