g(x) = 5.
So whatever f(x) or f(-1) is, g of that is going to be 5.
It is an equation and the value of x is 4
4x + 9 = 254x = 25 - 94 x = 16x= 16/4x= 4
4x=3x+1 => (4x-3x)=1 => x=1 therefore the value of x is 1.
3x + 8 = 4x + 23x - 4x = 2 - 8-x = -6x = 6
4x-5y = -8 4x+40 = y => y = 4x+40 Substitute the value of y into the top equation: 4x-5(4x+40) = -8 4x-20x-200 = -8 4x-20x = 200-8 -16x = 192 Divide both sides by -16 to find the value of x: x = -12 Substitute the value of x into the original equations to find the value of y: Therefore: x = -12 and y = -8
The value of x is 2
