Answer:
a = 43 / 30
Step-by-step explanation:
-7 ( 8a -9 ) = -23 + 4a
-56a + 63 = -23 +4a
-60a + 63 = -23
-60a = -86
a = 43 / 30
Answer:
x = 4
y = -7
Step-by-step explanation:
y = -2x + 1
4x + y = 9
4x + y = 9
4x + (-2x + 1) = 9
4x - 2x + 1 = 9
2x + 1 = 9
2x = 9 - 1
2x = 8
x = 8/2
<u>x = 4</u>
4x + y = 9
4(4) + y = 9
16 + y = 9
y = 9 - 16
<u>y = -7</u>
