Hi there, 3+-10=-7 so, -7+5x=13. First, we add -7 to both sides, which gives us 5x=13+7, 13+7=20, so 5x=20. Now, we divide both sides by 5, Therefore, x=4

Answer:
a=6 or -6
Step-by-step explanation:
Solve the determinant to get a²-36=0
(a-6)(a+6)=0
a=6 or -6
36/8=4.5 which is how many millimeters there are in a meter. So 6 meters *4.5 would be 27 millimeters. The length of the blue print is 27 millimeters
Answer:
the x and y is 6 and -4 respectively
Step-by-step explanation:
The computation of solving the system of equations is given below:
Given that
5x - 7y = 58
And,
y = -x + 2
Put y value in the first equation
5x - 7(-x + 2) = 58
5x + 7x - 14 = 58
12x = 58 + 14
12x = 72
x = 6
So y = -6 + 2
= -4
Hence, the x and y is 6 and -4 respectively
