The answer to 1/7 of 21 is 3.
I think x=10
4x=3x+10
subtract 3x from both sides and you get x=10
THE STEPS AND ANSWER IS IN THE PICTURE
12 × 12 =144+ 6 = 150 I'm pretty sure
Answer:
(4x + 3) + (-2x + 4) = 2x + 7
Step-by-step explanation:
(4x + 3) + (-2x + 4) = you then collect like terms
(4x + -2x) + (3 + 4)= like this, and you add what's inside perenthesis
= 2x + (3 + 4). step-by-step
= 2x + 7. then that is how you get =2x+7
