Four times a number increased by 3 is the same as twice the number increased by 9? I'm horrible at these

Answers

The question says:
4(x) +3 = 2(x) + 9 
so now you need to find x
first you should add -2(x) on both sides of the equation and then add -3 on both sides:
4(x) - 2(x) = 9 - 3 
2(x) = 6
now you can divide both sides by 2:
x = 6/2 
x = 3 :)))

Four times a number (we are gonna make that be "x") increased by 3 would be 4x+3 it says it is the same as (means it is equal to) twice the number (2x) increased by 9 (+9) so the full equation would be 4x+3=2x+9
You have to solve for the number (x).
4x+3=2x+9
-2x -2x (Have to get the x's to one side)
2x+3=9
-3 -3 (you have to get the numbers on one side too)
2x=6
/2 /2 (to get x alone)
X=3 (the number is 3)

Help please!! angle a and angle b are complementary angles. find angle a and angle b

angle a= x°
angle b= (2x+75)°

Answers

if ∡a and ∡b are complementary angles, that simply means that ∡a + ∡b = 90°.


a + b = 90

angle a= x°

angle b= (2x+75)°

3x + 75 = 90 subtract 75 from both sides

3x= 15 divide by 3

x=5

a = 5

5+b = 90 subtract 5 from both sides

b = 85
