Explanation

when you have two lines in a graph, the solution is the point where the line intersect each other, so to solve this we need to find that point

so, the answer is

$(1,-1)$

The measure of the supplement of an angle is 12 more than twice the measure of the angle. Find the measures of the angle and it'

astra-53 [7]

Supplementary angles add up to 180 degrees-

Let x = "the angle"

supplement angle = 2x + 12 // 12 more than twice the measurement of "the angle"

Supplement angle + "the angle" = 180 degrees

(2x + 12) + x = 180 degrees // 2x + 12 is the supplement angle

3x + 12 = 180 // Simplify

3x = 168 // Subtract 12 from both sides

x = 56 degrees // Divide both sides by 3

The measure of the angle is 56° and its supplement is 124°

How do you solve for x in a math question like this 5+4x=54-3x?

Bas_tet [7]

To solve for x, first you need to isolate all x terms on the same side so:

you start with 5 + 4x = 54 - 3x

subtract 5 from both sides to get 5 onto the left side

now you should have 4x = 49 - 3x

now add 3x to both sides to get 3x onto the right side

now you should have 7x = 49

now that you have your x on one side you can solve this like a regular one step equation and divide both sides by 7

this leads you to your answer of x = 7
