Subtract 7 from both sides.
1. 2x + 7 - 7 = x - 3 - 7
now the equation reads like this
2x = -10 + x
subtract x from both sides
2. 2x - x = -10 + x - x
now the equation reads like this
x = -10
then you have your answer
3. x = (-10)

gulaghasi [49]

Answer:

Step-by-step explanation:

If apricots is x, and each apricot weighs 5 grams, then the expression for that is 5x; if each cherry, y, weighs 2 grams, then the expression for that is 2y. If the mix Roy wants to make needs AT LEAST 230 grams of fruit, then

5x + 2y ≥ 230 where the inequality sign "greater than or equal to" satisfies the expression "at least".
