(х+104) *2=3х-70

Let's solve the equation step by step: \[ (х + 104) \cdot 2 = 3x - 70 \] First, distribute the 2 on the left side: \[ 2x + 208 = 3x - 70 \] Next, isolate the variable \(x\). Start by getting all terms containing \(x\) on one side and constant terms on the other side. Subtract \(2x\) from both sides: \[ 208 = 3x - 2x - 70 \] This simplifies to: \[ 208 = x - 70 \] Next, add 70 to both sides to isolate \(x\): \[ 208 + 70 = x \] \[ x = 278 \] So, the solution is: \[ \boxed{278} \]
