Equals anything... x is a variable. If that equation was set equal to zero then you could solve for x, but that is not what you have asked.
The equation is -2y + 16 = 10
From second equation: y = 8 + 2xSubstitute for y in first equation: 3x + 16 + 4x = 2ie 7x = -14ie x = -2 and y = 4
-6z + 16 = 52 subtract 16 from each side -6z = 36 divide by -6 z = -6
h = 63

a+b=16 is a linear equation in two variables. The variables are a and b. To solve a linear equation in 2 variables we need more information. We need either another equation, or a value to put in for a or b.Since we have neither, there is no more we can do.
x = -8
20
4x = 16Divide each side of the equation by 4:x = 4
It is an equation and the value of a is 16
It is an equation and the value of x is 7
a-16 = a/4+2 Multiply all terms by 4: 4a-64 = a+8 4a-a = 8+64 3a = 72 a = 24
