4m + 9 + 5m - 12 = 42
Combining like terms to both sides:9m=42+12-9=>9m=45
divide both side by 9:m=5;
Given y = 2x + 4, plug in x = 42 and simplify: y = 2(42) + 4 y = 84 + 4 y = 88
42 + 42 = 84
To simplify the equation (4m + 9 + 5m - 12 = 42), combine like terms: ( (4m + 5m) + (9 - 12) = 42) simplifies to (9m - 3 = 42). Next, add 3 to both sides: (9m = 45). Finally, divide by 9 to find (m = 5).

28 + 42 = 70
Given y = 2x + 4, plug in x = 42 and simplify: y = 2(42) + 4 y = 84 + 4 y = 88
4m + 9 + 5m - 12 = 42 9m -3 = 42 9m = 42 + 3 9m = 45 m = 5
42 + 42 = 84
