4) easy- solve for x

- 8

Step-by-step explanation:

x/4 - 5 = -7

=> x/4 = -2

=> x = -8

x=−8

Step-by-step explanation:

Add 5 to both sides

x/4-5+5=-7+5

x/4=-2

4x/4=4(-2)

x=-8

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
