Which steps would you use to solve this equation? Check all that apply. p + 7 = 12 Subtract 7 from both sides of the equation. Subtract 7 from 7. 7 – 7 = 0 and 12 – 7 = 5, so p = 5. Substitute 12 for p to check the solution. Substitute 5 for p to check the solution.

Subtract 7 from both sides of the equation.

Step-by-step explanation:

Hi, to answer this question we have to solve the equation given for p:

p + 7 = 12

Subtracting 7 from both sides of the equation:

p+7-7 = 12-7

p = 5

So, the correct option is Subtracting 7 from both sides of the equation.

alright so i think for this one it would to draw it out. this may be hard for me to try and draw, but i will do my best on here:

        r

  /       |     \

notice how it forms 2 triangles inside one bigger triangle.

so if we know the angle spr is the same as psr that is saying the measure of angle p is the same as angle s. this means the big triangle psr is either isosceles or equilateral. in both cases, the triangle is perfectly symmetrical when split down the middle, which is in this case rq. because we know it is perfectly symmetrical on both sides, we know that the two triangles inside the bigger one are equal.
