4x - 5 for x = 4

4*4 - 5 = 11

200

2a + 5 for a = 3

2 * 3 + 5 = 11

300

3(2y - 1) + 6 for y = 2

3(2 (2) - 1) + 6 = 15

400

3(6 - b) + 7 - 2b for b = 4

3(6 - 4) + 7 - 2(4) = 5

500

n/4 + 2n - 3 for n = 8

8/4 + 2(8) - 3 = 15

Expressions w/Exponents

6x^2 - 10 for x = 4

6(4)^2 - 10 = 86

200

4(t) + 5 + t^2 for t = 3

4(3) + 5 + (3)^2 = 26

300

3s^3 + 7 - 2s for s = 4

3(4)^3 + 7 - 2(4) = 191

400

x^3+ y^2 - z^1 for x = 2, y = 5, z =4

22(2)^3 + 5^2 - 4^1= 37

500

2x^4 + 5L^7 - 6w^3 - 4m^2 for x = 3, L = 6, w = 4, m = 5

2(3)^4 + 5(7)^8 - 6(4)^3 - 4(5)^2 = 2(81) + 5(279936) - 6(64) - 4(25) = 162 + 1399680 - 384 - 100 = 1399358

6z^2 - x for z = 3, x = 7

6(3)^2 - 7= 47

200

3x^4 - z for x = 3, z = 10

3(3)^4 - 10 = 233

300

6L^3 - 8W^4 for L = 9, W = 2

6(9)^3 - 8(2)^4 = 4246

400

5a^3 - 10b^2 + 100c^500 for a = 3, b = 2, c = 1

5(3)^3 - 10(2)^2 +100(1)^500 = 195

500

n^2/4 + 2m^3 - 85 for n = 8, m = 3

(8^2)/4 + 2(3)^3 - 85 = -15
