Answer 4

Solve 5−6x=−7 .(1 point) x=

Answer 5

To solve the equation 5−6x=−7, we can follow these steps:

Step 1: Start with the equation: 5-6x = -7

Step 2: Subtract 5 from both sides of the equation:

(5 - 6x) - 5 = -7 - 5

Simplifying: -6x = -12

Step 3: Divide both sides of the equation by -6:

(-6x) / -6 = -12 / -6

Simplifying: x = 2

Hence, the solution to the equation 5−6x=−7 is x = 2.

Answer 6

The equation 5/3x+11/3=−4/3 is solved as follows. Fill in the correct numbers to complete the solution.(1 point) 5/3x+11/3=−4/3 5/3x= Subtract 113 from both sides. x= Multiply both sides by 3/5 , the reciprocal of 5/3 .

Answer 7

To solve the equation 5/3x+11/3=−4/3, we can follow these steps:

Step 1: Start with the equation: 5/3x + 11/3 = -4/3

Step 2: Subtract 11/3 from both sides of the equation:

(5/3x + 11/3) - 11/3 = -4/3 - 11/3

Simplifying: 5/3x = -15/3

Step 3: Multiply both sides of the equation by 3/5, the reciprocal of 5/3:

(5/3x)(3/5) = (-15/3)(3/5)

Simplifying: x = -45/15

Step 4: Simplify the fraction:

x = -3

Hence, the solution to the equation 5/3x+11/3=−4/3 is x = -3.
