Find x when y = 5 in the literal equation 4x + 7y= 51.

x=4

Step-by-step explanation:

4x + 7y= 51

We replace y by 5 and determine x.

4x+7×5=51

4x+35=51

4x=51-35

4x=16

x=4

x = 4

Step-by-step explanation:

Step 1:  Substitute 5 for y and solve

4x + 7(5) = 51

4x + 35 = 51

Step 2:  Subtract 35 from both sides

4x + 35 - 35 = 51 - 35

4x = 16

Step 3:  Divide both sides by 4

4x / 4 = 16 / 4

x = 4

 x = 4

step-by-step explanation:

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
