Find the value of x 5x+6-2=9
a.1
b.5
c.3/7 fraction
d. 5/7 fraction

A

Step-by-step explanation:

Given

5x + 6 - 2 = 9, that is

5x + 4 = 9 ( subtract 4 from both sides )

5x = 5 ( divide both sides by 5 )

x = 1 → A

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

f(x) = y

f(-3) = -5
