Answer:
x=7
y=-17
Step-by-step explanation:
Lets do 10x-7. Basically it will be equal to 63, so the equation will be 10x-7=63
to find x we need to add 63+7=70 and put 10x with an equal sign which is 70=10x
7=x because 70/10=7.
in a simple way it is
10x-7=63
10x=7+63=70
10x=70
x=7
Lets do -5y+3. It is equal to 88.
so it will be
-5y+3=88
-5y=88-3=85
-5y=85
y=-17
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.
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]
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]
