What is the value of x?
45°
( 2x-5)°

(2x - 5)° + 45° = 180°

2x° + (-5 + 45)° = 180°

2x° + 40° = 180°

2x° = 180° - 40°

2x° = 140°

x° = 140 ÷ 2

x° = 70°

So, the value of x is 70°

Hope it helps and is useful :)

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
