4r + 13 = 57subtract 13 from both sides:4r + 13 - 13 = 57 -134r = 44divide both sides by 4 to solve for r:4r/4 = 44/4r = 11
9y subtract 11 equals 7
It is 4r + 12s
-2=4r+s s=-4r-2 or s=-(4r+2)
Since 4R and R both contain a like term (R), you can combine them: 5R would be 4R plus R simplified
It is in its simplest form: 4r+r = 5r
s = -2 -4r
The question contains an algebraic expression. It is not an equation (or inequality) and so cannot be solved.
so 26 = 4r so r = 6½
4r + 8rs + 28r 4r is a factor of every every term so the expression can be written 4r(1 + 2s +7) NOTE : The original expression can be simplified to 8rs + 32r and thus the factored expression becomes 4r(2s + 8).
3q+4r-s+5q-6r+2s
