How do you solve 4y plus x equals 8
0
x=28
To solve for x, we'd have to know what this expression equals.
ax - b = c ax = b + c x = (b + c)/a
axx+bx+c 2xx+7x+6a=2b=7c=6Multiply a and c:2*6=12Find multiples of ac that add up to b (d,e [ie de=ac, d+e=b]):12=2*2*312=4*3, -4*-312=6*2, -6*-2Rewrite axx+bx+c into axx+dx+ex+c:2xx+7x+62xx+4x+3x+6Factor sets of terms (ie axx+dx, and ex+c):2xx+4x+3x+62x(x+2)+3(x+2)Combine like terms:2x(x+2)+3(x+2)(x+2)(2x+3)

multiply a by x then add the product of c and y. Your answer would be, based on the value of a,x,c,y, like this.ax + cy = ??
X +13 equals 22, X equals nine
x=1
x=b-a
x=28
