Solve: 2(23 + a) = 34

a = −6

Step-by-step explanation:

Step 1: You should divide both sides by 2.

Step 2: then simplify into 17.

23 + a = 17

Step 3: next, you need to subtract 23 from both sides.

a = 17 − 23

Step 4: lastly, Simplify 17 − 23 to −6 and you're done!

a = −6

a = -6

Step-by-step explanation:

2 (23 + a) = 34

46 + 2a = 34

2a = 34 - 46

2a = - 12

a = - 12/2

a = - 6

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
