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
h = 16 16-9 = 7
From second equation: y = 8 + 2xSubstitute for y in first equation: 3x + 16 + 4x = 2ie 7x = -14ie x = -2 and y = 4
x = -8
-6z + 16 = 52 subtract 16 from each side -6z = 36 divide by -6 z = -6
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.
It is an equation and the value of a is 16
It is an equation and the value of x is 7
4x = 16Divide each side of the equation by 4:x = 4
