Answer:
D) Multiply A by -4 and B by 5
Step-by-step explanation:
5x-2y=10
4x+3y=7
----------------
-4(5x-2y)=-4(10)
5(4x+3y)=5(7)
----------------------
-20x+8y=-40
20x+15y=35
---------------------
23y=-5
y=-5/23
5x-2(-5/23)=10
5x+10/23=10
5x=10-10/23
5x=230/23-10/23
5x=220/23
x=(220/23)/5
x=(220/23)(1/5)
x=220/115
x=44/23
Answer:
23
Step-by-step explanation:
- Create an equation to find y: 3 =

- Calculate by adding: 3 =

- Multiply both sides of the equation by 7 : 21 = y - 2
- Move the variable to the left-hand side and change its sign : -y + 21 = -2
- Calculate and change signs : y = 23
y = 23
