3x+4=-4×3x solve and show work : )

Hello!

Step 1. Simplify the equation... 3x+4-12x

Step 2. Add 12x to both sides... 3x+4+12x=−12x+12x

15x+4=0

Step 3. Subtract 4 from both sides... 15x+4−4=0−4

15x=-4

Step 4. Divide both sides by 15...15x/15=−4/15

X=-4/15

Final x=-4/15

Hope I could help! :)

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
