Answer:
y = -2x + 3
Step-by-step explanation:
4x + 2y = 6
⇔ 2y = 
Answer:
x=12 and
(9*12)-10=98
(5*12)+38=98
both angles are = 98
Step-by-step explanation:
do this :
9x - 10 = 5x + 38
( - 5x from both sides)
4x - 10 = 38
(add 10 to both sides)
4x = 38+10
4x=48
(divide by 4)
x=48/4
= 12
substitute into the equations:
(9*12)-10
(5*12)+38
Answer:
x/-9 = -16 ; 144
Step-by-step explanation:
x is the variable for "a number". It is being divided by -9, so x must be divided by -9. The number divided by -9 equals -16, so -16 must go on the other side of the equation. To solve, multiply both sides by -9 to cancel out the fraction and isolate the variable.
Well it says SQUARE so in a square all sides are equivalent so it will be 3x3 and that will hy your answer (y=3)
In the first one it would be (21-8)-6=7.
and in the second one it would be 21-(8-6)=19
