4r+4g

It is (7 + a)r.

2r + 2s = 50 2r - s = 17 therefore 4r - 2s = 34 Add so that you can eliminate one of the variables: 2r + 2s = 50 4r - 2s = 34 ---------------- 6r + 0s = 84 Solve for r: 6r = 84 r = 14 Substitute r into one of the original equations: 2(14) + 2s = 50 28 + 2s = 50 2s = 22 s = 11 Doublecheck with the other original equation: 2(14) - 11 = 28 - 11 = 17

2r + 7r - 6t - r + 7t = 8r + t

(r + 5)/b

4r + 4 = 5r 4r - r = 3r 4r x r = 4r^2 4r/r = 4

Since 4R and R both contain a like term (R), you can combine them: 5R would be 4R plus R simplified

4r+4g

-13

(r + 2)(r + 2)

If you mean: 10+4r = 30 then it works out that r = 5

r=8

It simplifies to: 2s+4R

It is (7 + a)r.

-4r+6=14 isn't an inequality, its a linear equation. Anyway... -4r+6=14 (-6) -4r=8 (/4) -r=2 (x-1) r=-2

-2 - 2r or -2(1 - r)

so 26 = 4r so r = 6½
