Answer :
Steps:
1. Substitute the y in 4x + 10 with -5x-10
-5x-10= 4x + 10
2. Add 5x on both sides
-10= 9x + 10
3. Subtract 10 on both sides
-20= 9x
4. Divide by 9 on both sides
5. Your answer is
X= -20/9
1. Substitute the y in 4x + 10 with -5x-10
-5x-10= 4x + 10
2. Add 5x on both sides
-10= 9x + 10
3. Subtract 10 on both sides
-20= 9x
4. Divide by 9 on both sides
5. Your answer is
X= -20/9
[tex]y=4x+10\\
y=-5x-10\\\\
4x+10=-5x-10\\
9x=-20\\
x=-\frac{20}{9}\\\\
y=4\cdot(-\frac{20}{9})+10\\
y=-\frac{80}{9}+\frac{90}{9}\\
y=\frac{10}{9}\\[/tex]
