Answer:
[tex]\Longrightarrow: \boxed{\sf{x=7, \ y=-17}}[/tex]
Step-by-step explanation:
To find the value of x and y in the parallelogram, you have to isolate it on one side of the equation.
10x-7=63
First, add by 7 from both sides.
10x-7+7=63+7
Solve.
Add the numbers from left to right.
63+7=70
10x=70
Then, you divide by 10 from both sides.
10x/10=70/10
Solve.
Divide these numbers goes from left to right.
70/10=7
[tex]\Longrightarrow: \boxed{\sf{x=7}}[/tex]
-5y+3=88
Subtract by 3 from both sides.
-5y+3-3=88-3
Solve.
Subtract the numbers from left to right.
88-3=85
-5y=85
Divide by -5 from both sides.
-5y/-5=85/-5
Solve.
Divide the numbers from left to right.
85/-5=-17
[tex]\Longrightarrow: \boxed{\sf{y=-17}}[/tex]
- Therefore, the correct answer is x=7 and y=-17.
